[Edaily Reporter Kim Hyun-ah] With the full implementation of the “National Cybersecurity Basic Guidelines” beginning on the 1st of last month, the public information security system is reaching a new turning point. This reflects the assessment that, as the scope of data utilization expands rapidly due to the spread of artificial intelligence (AI) and cloud computing, it is difficult to achieve both digital innovation and security through existing uniform network segmentation policies alone.

At the heart of this overhaul is the National Network Security Framework (N2SF). The N2SF is a data-centric next-generation security model that moves away from the existing one-size-fits-all network segmentation approach to apply security policies differentially based on the importance of data and systems. Its core principle is to classify business information and systems into Confidential (C), Sensitive (S), and Open (O) levels and to control access and transmission based on user classification.

The Key to N2SF Transition: ‘Integrated Platform’

For a successful transition to N2SF, a macro-level platform is required that not only enables granular data control but also allows for the integrated monitoring and control of the entire security system.

AI security specialist #Igloo Corporation presents ‘SPiDER ExD,’ an AI-based hybrid extensible detection and response (XDR) platform, as the solution to achieve this. Igloo Corporation has demonstrated its capability to implement next-generation security architectures by participating in a national network security system pilot project for government integrated platforms.

SPiDER ExD uses standardized APIs to integrate heterogeneous solutions distributed across on-premises and cloud environments, enabling unified monitoring and management from a single dashboard. It collects various data—including logs, events, assets, security status, policies, and vulnerabilities—to provide end-to-end security visibility.

It also manages the security rating history for each of the six core pillars of Zero Trust and enhances security operations efficiency by applying AI analysis and Security Orchestration, Automation, and Response (SOAR) technology.

“See and Verify for Yourself”… N2SF Demo Room in Operation

Igloo Corporation is also focusing on establishing a hands-on support system to reduce the burden on customers during the N2SF transition process.

The company has set up an “N2SF Demo Room” at its headquarters that replicates an actual public cloud environment, enabling customers to pre-check the effectiveness of the new security framework and verify it firsthand. The company explains that this helps alleviate vague concerns about adopting N2SF and allows customers to confirm specific operational plans.

In addition, the company plans to operate a support system to review key requirements in preparation for the revised cybersecurity assessment indicators. The goal is to provide a practical support system that covers everything from technology adoption to post-implementation evaluation.

Competition Heats Up in Data Classification and CDS Fields

In line with the expansion of the N2SF market, security companies are strengthening their response solutions in their respective areas of expertise.

SoftCamp is focusing on the data identification and classification sector. Through its AI-based document classification solution, ‘InfoDiscovery,’ it automatically identifies vast amounts of documents within an organization and assigns security ratings.

It is also building a data-centric protection system by integrating ‘InfoLineage’ technology, which tracks whether a document’s name has been changed, its movement path, and its transmission history across networks.

HuneSion is targeting the Cross-Domain Solution (CDS) market. Through ‘Transfer CDS,’ an evolution of existing network interconnection solutions, it supports both bidirectional and unidirectional data transmission.

In particular, the company is focusing on preventing the external leakage of high-security-level information by implementing ‘domain-aware transfer technology,’ which uses an intelligent policy engine to automatically identify data security classifications and control data flow.

Public Security Market: From ‘Network Segmentation’ to the ‘Data Security’ Era

The security industry anticipates that the competitive landscape of the public security market will undergo a fundamental shift following the implementation of N2SF.

While network segmentation solutions and network security equipment were the main focus in the past, data classification, access control, zero-trust, XDR (extended detection and response), CDS (cross-domain solutions), and AI-based security analytics are likely to become key competitive advantages moving forward.

A security industry official stated, “The essence of N2SF is not simply connecting networks, but designing security based on data,” adding, “The capability of an integrated platform that can track in real time who is accessing data and what data is being moved where will become increasingly important.”

It remains to be seen whether domestic security firms, including Igloo Corporation, will be able to secure new growth opportunities during the transition of public institutions to N2SF.
